This reads like somebody based ELIZA on Monty Python's argument clinic instead of a therapist. Alert fatigue kicks in easily under the best circumstances, and "an annoying bot cluttering a group text" is hardly the best of circumstances. If the bot limited itself to high-confidence assertions that a claim is factually false, I'd be interested. (I wouldn't use it, the social and privacy aspects guarantee that, but I'd be interested in the tech.) But "not all information about water is credible" isn't fact-checking; it's a tool you could duplicate with keyword recognition and a list of random stock refutations. Maybe I'm overzealous, but I'd consider removing an actual human from a group-chat if they consistently made that sort of post.
